Make x the subject of these equations.

shepuryov [24]

$(1)a(x + b) = c \\ ax + ab = c \\ ax = c - ab \\ \frac{ax}{a } = \frac{c - ab}{a} \\ x = \frac{c - ab}{a}$

$(2)8(x + a) = b \\ 8x + 8a = b \\ 8x = b - 8a \\ \frac{8x}{8} = \frac{b - 8a}{8} \\ x = \frac{b - 8a}{8}$

$(3)a(x - 7) = b \\ ax - 7a = b \\ ax = b + 7a \\ \frac{ax}{a} = \frac{b + 7a}{a} \\ x = \frac{b + 7a}{a}$

$(4)c(2 + x) = 6 \\ 2c + cx = 6 \\ cx = 6 - 2c \\ \frac{cx}{c} = \frac{6 - 2c}{c} \\ x = \frac{6 - 2c}{c}$

Can you guys help me with this?

Blababa [14]

Answer:

We have been given many sequences below:

The sequence is said to be geometric if there is same ratio between consecutive terms

$\frac{a_n}{a_{n-1}}$

So we will check all the sequences one by one:

(1) $\frac{-9}{-2.7}=\frac{10}{3}$

$\frac{-30}{-9}=\frac{10}{3}$

$\frac{-100}{-30}=\frac{10}{3}$ .

Hence, geometric

(2) $\frac{2.5}{-1}=-2.5$

$\frac{-6.25}{2.5}=-2.5$

$\frac{15.625}{-6.25}=-2.5$

Hence, geometric.

(3) $\frac{9.2}{9.1}=0.010$

$\frac{9.3}{9.2}=0.010$

$\frac{9.4}{9.3}=0.010$

Hence, geometric.

(4) $\frac{0.8}{8}=0.1$

$\frac{0.08}{0.8}=0.1$

$\frac{0.008}{0.08}=0.1$

Hence, geometric.

(5) $\frac{-4}{4}=-1$

$\frac{-12}{-4}=3$

Ratio is not same hence, not geometric.
